That's a cool find! I love finding plants or flowers that grow out of cracks in the rocks or concrete. It's inspiring and is a good example of how life often finds a way through adversity and difficult places. Neat shot. Also I recently found out those Indian Paintbrush flowers are edible, they taste pretty good. Though you're not suppose to eat too many of them because they can be toxic if you eat too many.
I thought you would like this one, it's right up your alley. Natures nuances! It sounds exotic eating flowers, I might have to try it.
